Homeowners Beware! Roof Moss Can Spell Insurance Cancellation

Some homeowners see moss on their roof as nothing more than an eyesore. But did you know that you could lose your homeowner’s insurance if there’s moss growing on your roof?

More and more folks have been learning that when they get a surprise letter from their insurance company telling them to clean up or else.

Read on to hear one homeowner’s story and to learn how to get rid of moss the easy way!

The Shocker: Clean up or Ship out!

When you buy your homeowner’s insurance policy, the company checks things such as how far your house is from the nearest fire hydrant, whether or not you have smoke detectors, and whether you have pets.

But not everyone realizes that insurance companies can send inspectors out to look at the outside of your home at any time, even years after you buy the policy, to see if something has changed that will make them want to increase your premium or cancel your coverage.

One of the things that can cause you big problems is moss. Check out the video above to hear what Bob’s insurance company said to him.

Why is Moss Such a Big Deal?

Moss might be tiny, but it packs a lot of trouble in its little green mass. Moss has root-like structures that adhere to your roof’s surface, causing pitting in many types of shingles and causing asphalt shingles to lose their protective granules.

Moss also likes to grow in the spaces around and underneath shingles (see the photo at the top of this article), causing the shingles to pull away from the roof’s membrane as the moss grows thicker.

All of these things lead to a breakdown in your roof’s integrity, which leads to water leaks and water damage. And if there’s one phrase that insurance companies hate to hear, it’s “water damage.”

Roof leaks are the number-one cause of water damage, and your insurance company doesn’t want to pay for more costly water damage claims. So if they see moss on your roof, they just might throw a red flag and you could get a letter.

How to Get Rid of Roof Moss

There are a few ways to get rid of moss on your roof. Some people use a pressure washer, which can tear shingles or rain gutters loose, force water into spaces where it doesn’t belong, and blast protective granules off of asphalt shingles.

Others use a bleach solution, which requires scrubbing and rinsing, and can corrode your downspouts and kill your lawn with caustic runoff. Worst of all, neither pressure washing nor bleaching does anything to keep moss from growing right back, so you have to keep cleaning over and over again.

Wet & Forget Hose End wipes out roof moss with no scrubbing, bleaching or pressure washing needed. Just spray and leave! Its gentle non-caustic formula is safe to use on all types of roofs, and the runoff won’t harm your downspouts or lawn.

Best of all, Wet & Forget Outdoor works with the wind and rain to keep moss away for a year or more in most cases! Here’s how to eliminate moss with Wet & Forget Outdoor Hose End:

  1. Attach Wet & Forget Hose End to your garden hose and turn the water spigot on.
  2. Attach the jet setting tip to the sprayer and turn the dial to the “WATER” setting. Rinse nearby plants and landscaping with water to protect them from any potential overspray.
  3. Turn the dial to the “ON” setting and spray the affected area with the diluted Wet & Forget Outdoor at a time that allows 4 to 5 hours’ drying time before the chance of rain. Saturate the moss thoroughly so that the solution can penetrate the moss’s root-like structures.
  4. Turn the dial to the “WATER” setting and rinse nearby plants and landscaping.
  5. Walk away, and let Wet & Forget Outdoor do the work for you!
  6. Re-treat once a year, or at the first sign of re-growth.

Note: Be very careful walking on your roof, as moss and wet surfaces can be slippery. If you don’t feel comfortable walking on your roof, call a professional.

Wet & Forget Outdoor also eliminates green algae, black algae, mold and mildew, and lichen! Click here for special instructions for treating lichen.

  1. Good Morning. Do you have a recommendation for the best long distance sprayer I can use with this product, which by the way I have used for several years and really like. I want to spray the eaves of my house without having to spend too much time on a ladder. Thank you so much for any information you can provide.

    1. Hi Lindsay,
      We’re happy to have you as one of our longtime customers. There’s a type of sprayer called a Trombone Sprayer that will get you a much greater distance from the ground than a garden pump sprayer would. These sprayers have a tube that you would put into a premixed bucket of Wet & Forget and you would pull directly with the tube. This should get you an extra 15-20ft of spraying distance.
